This invention relates to shields for use in seen that these twosections of colored glass are electric welding, for shielding the eyesagainst beveled at their edges 8, to t together as shown the glare of anelectric arc, or for shielding the in Fig. 2 of the drawing, when thesection 1 is in eyes against any other light, wherever such is itsnormal position.

Thus, the opening and closing of fixed position, and a lowersection 1 of colored the clear view window, afforded between the twoglass, adapted to move up and down between thev sections ofv coloredglass, may alternate with the two sections 4 and 5of clear glass. Itwill be openingv and closing of the electric circuit. In 65 this way,the worker may alternately have protection against the ultra-violetrays, through the medium of the colored glass, and a clear andunobstructed view of the work, through practically one and the samewindow in the front of the shield, thus obviating the necessity ofmoving the shield to one side when a clear view of the work is desired.

It will be understood, of course, that the handle 2, instead of beingheld in the hand, may be supported on a stationary support, or onsomething supported by the head or shoulders of the worker. On the otherhand, the handle 2 may be omitted, and the shield may be supported insome other manner, so that the worker will be left free to use bothhands on the work being done. In such case, the invention is of specialvalue, as it obviates the necessity of removing the shield from in frontof the face of the worker, in order that the latter may have a clearview of the work irom time to time, when the circuit is open and theelectric are is not at work.

It will also be understood that any suitable or desired means can beemployed for controlling the sliding movement of the section l. ofcolored glass. As shown, such means are manually operable by the hand,but it is obvious that this can be done by other things, includingfoot-control, and particularly so in connection with a shield of thiskind that is supported on the head or shoulders of the worker, or onsome stationary support that is not held in the hand.

As with the ordinary shield, when the worker looks through the windowformed by the sections of glass, some things are barely visible throughthe colored glass, when the edges 8 are tight together, suiiiciently soto enable the worker to do the desired work. But, when the edges 8 areseparated, there is then complete visibility through the space formed,in a manner necessary for certain steps in the work.

It will be seen, therefore, that the section 6 of colored or shadedglass is stationary, as it is xed in position in the window, and hencethis section is always in position for vision therethrough regardless ofwhether the section 'I is down or in normal position. When the section Iis down a distance to provide an area of `clear vision, a slightrelative movement as between the head and the shield body I is sucientto instantly bring the line of vision through the stationary section 6,if such is desired. The spring I3, it will be seen, is capable of movingand maintaining the section 'I in normal position, and in this way theclear vision area cannot accidentally be left open. When the section Iis up in normal position, with the beveled edges 8 tight together, thereis an ample area of protected vision, practically throughout the area ofthe window. However, even if this section I is clear down, even lowerthan the position shown in Fig. '7, there is still the area of protectedvision provided by the section E, as the latteris stationary or xed inposition in the upper portion of the window.

It will be seen that the housing I5, on the front of the shield I,contains the rod and the spring I3 for operating the movable glass 'I,in the manner described. This housing I5 extends vdownwardly from thebottom of the framing 3 dangerous or injurious rays of an electric arc,-as in electric welding, comprising means forming the body of the shield,means forming a framed window in the front of said body, having coloredor shaded glass to protect the eyes against said rays, movable means forproducing a clear vision area in said window, of variable height and xedhorizontal length from one side of the window to the other, between theupper and lower edges of said window, causing a variable area of shadedglass between the upper and lower edges of the window, as well as avariable area of clear vision, and enclosed spring means entirelyexternal of said body and carried by the latter below the middle of saidwindow, capable of moving and maintaining said movable means in normalposition, together with means outside said body and operable forovercoming the tension of said spring means, when said clear area. isdesired.
